Foldable Display Cover Member with Separable Cutting Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules face challenges in reducing manufacturing costs while maintaining protection for the display unit from external impacts and scratches.
Innovation Solution
A display module design featuring a cover member with a cutting part that is separable from the cover member and overlaps with a portion of the folding axis, along with a cover pad attached via an adhesive part, which allows for reduced manufacturing costs by omitting additional liners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional liners are added to the cover member to maintain protection, then protection reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent merges the functions of multiple liners into a single integrated cover member. The cover member includes a body portion and a cutting part that are formed as one piece, eliminating the need for separate liners while maintaining the protective function. This reduces structural complexity and manufacturing cost while preserving protection reliability.
Solution Approach 2:
The cover member is designed to perform multiple functions: it protects the display unit from external impacts, provides a folding structure that allows the display device to be folded, and includes a cutting part that can be separated to expose the bending part. This multi-functionality eliminates the need for additional protective components.
2Strength
If additional liners are added to the cover member, then protection from external impacts is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple protective layers into a single cover member structure. The cover member body portion provides the primary protection, while the integrated cutting part allows for cost-effective manufacturing by eliminating the need for separate liner components and their associated assembly processes.
Solution Approach 2:
The cover member is segmented into a body portion and a cutting part that can be separated. This segmentation allows the cutting part to be removed to expose the bending part of the display unit, providing functional flexibility while maintaining protection strength through the integrated structure during manufacturing.
3Ease of manufacture
If the cover member structure is simplified to reduce cost, then manufacturing cost is reduced, but protection capability may be compromised
Solution Approach 1:
The simplified cover member structure maintains full protection capability by integrating multiple functions into a single component. The cover member body portion provides impact protection, the cutting part enables selective exposure of the bending part, and the overall structure supports the folding function, all without requiring additional protective components.
Solution Approach 2:
The patent merges protection, folding support, and selective exposure functions into a single cover member structure. This integrated design reduces manufacturing cost by eliminating multiple separate components while maintaining comprehensive protection capability against external impacts and scratches.
